Heavy duty engines. Measurement of gaseous emissions from raw exhaust gas and of particulate emissions using partial flow dilution systems under transient test conditions LONG_TITLE BS 7121-1 is Part 11 Scope This International Standard specifies methods for the measurement and evaluation of gaseous and particulate exhaust emissions from heavy duty engines under transient conditions on a test bed. The procedures it defines can be applied to any transient test cycle that does not require extreme system response times; it can therefore be used as an option to the regulated measurement equipment of certification test cycles usually CVS type systems
